A Long Island shrink who got a dental implant through a multimillion-dollar ring that allegedly harvested body parts without consent from relatives of the deceased is suing for $5 million, The Post has learned.

Evelyn Liegner, of Great Neck, alleges that the grisly transplant has had a “serious detrimental effect on [her] mental and physical health, enjoyment of her life, and her longstanding relationship with her husband,” according to the lawsuit in Brooklyn federal court.
